Is it really only computation:

The reallity of making a computer is`nt that hard to understand it was all about making a machine that is so very fast and calculating in nature.Today we can see that computers not only perform calculation or calculating work but also perform a lots of other works so we just can not blame only calculation to be responsilble for the definition of the computer.In fact these other works are 80% of all the works performed by a computer so there is only 20% works remain that are performed by computer and that are calculating works.Other 80% of works performed by computer are ofcourse  of non-numerical nature.So the true definition of computer as we saw does not come from the calculating works so if more accurately we define a computer then we will say that it is a kind of machine that operates itself on the data or information given to it.
